Abstract

This research investigates the transmission and reception of signals over the High Frequency (HF) band. HF communications are useful over long distances, but experience performance problems such as channel fading and low data rates. Our project researches the viability of using left- and right-handed circular polarized signals to increase data rates and link reliability. Two project sites are used for testing and use a cross-dipole antenna setup, and the Ettus Universal Software Radio Peripheral (USRP) software defined radio for transmission and reception. The project will evaluate whether the implemented setup allows for the left- and right-hand polarized signals to be separated at the receiver, which is important for reliable communications, less fading, and increased data rate.
